Hello,
We are sorry for this return but normally this should already be the case, if your customer leaves his basket, then comes back (by login) normally he will find his cart, either in a cart module or in his user panel.
On the backend, you can find abandoned cart, from Main HikaShop Configuration, Customers dropdown => Cart
Can you elaborate more your answer by providing these elements :
- An url link to your website
- How do you process your test (step by step process) ?
Awaiting your element to progress on your website.
Regards
